Here's the crack for Call of Duty 2 v1.00
It works well for me.
If you don't know how to place a crack:
Step 1: copy the crack
Step 2: Find where you installed Call of Duty 2
Step 3: Paste the crack and replace the other .exe
-----Information-----
Personnaly i have the original game, i'm only doing crack for fun and i think
you should buy the original too cause the original is always better than a copy
of it. I'm making crack to help you play your games.
